Code of the calendar visualization nicely split into functions.
Using CDN for Underscore & D3.
Drawing one full red box for every day with a workout.
Workout boxes with size corresponding to workout time.
Workout boxes with colors for different exercise types.
Computing prefix sums and changing drawing orders so that multiple exercises per day are visible.
Argument switch between visualizing time/distance.

Cleanup in linked in CSS/JS (using jscdn, instead of the course links).
First (not very pretty) go at calendar visualization controls.
